<?xml version="1.0" encoding="utf-8" ?>
<ContentView    
    xmlns="http://xamarin.com/schemas/2014/forms"
    x:Class="App5.Views.Self_Trainig"

    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
  
    NavigationPage.HasNavigationBar="False">

    <ContentView.Resources>
        <ResourceDictionary>
    ............
        </ResourceDictionary>
    </ContentView.Resources>

    <ContentView.Content>

Answer 1

<ContentPage
    xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:mynamespace=clr-namespace:App5.Views" 
    ...>
...
    <tabView:SfTabItem.Content>
        <mynamespace:Self_Trainig ... />
    </tabView:SfTabItem.Content>

Explanation:

• Add an xmlns:... definition for the namespace your ContentView is in.
• Add an element with that namespace and the class name of your ContentView.
• ...: After the class name, you can add any needed attributes. Just like any other ContentView.
